Bug ID: 107739
Summary: --enable-languages= duplicates yield odd error
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: aldot at gcc dot gnu.org
Target Milestone: ---
Mere cosmetics, but the error is contradicting it's own hint in a confusing
way.
$ ../../src/gcc-13.mine/configure --enable-languages=c++,lto,lto
configure: error:
The following requested languages could not be built: lto
Supported languages are: c,c,c++,fortran,go,lto,objc,obj-c++
or other dups like
$ ../../src/gcc-13.mine/configure --enable-languages=c++,c++,lto
configure: error:
The following requested languages could not be built: c++
Supported languages are: c,c,c++,fortran,go,lto,objc,obj-c++
I'm not sure why duplicates are not ignored silently.
